[Prolongation of premature multiple pregnancy after abortion of one or more fetuses].

In four cases of one twin pregnancy and three triplet pregnancies, efforts were made to prolong the pregnancy after the death of one foetus between 15th and 26th weeks of gestation. Two patients had a history of spontaneous abortion, three patients had undergone infertility treatment. In a further three cases the membranes ruptured prematurely in association with severe disturbance of the vaginal flora. Treatment consisted of rest in bed, sedation, and administration of magnesium and antibiotics. Neither cervical cerclage nor general IV tocolysis were performed. Although the pregnancies could be prolonged for 4, 22, 28, and 76 days, they all terminated before the 27th week, mainly due to ascending infection. Of the 11 children, two survived with no morbidity, two children (B and C of the third triplet pregnancy), died 2 and 19 days after delivery, respectively, and seven were stillborn. A comparison with prolongations of twelve twin and four triplet pregnancies reported in the literature, reveals the various concepts for treatment. After infection has been ruled out and the parents have been fully informed, efforts could be made to prolong the multiple pregnancy after the death of one foetus until the surviving child is viable. This requires intensive supervision.
